Guten Morgen JohnJ !
It is winter in Germany, it was snowing last night, but now the cold sun is shining again. Time for some electronic music with "Kraftwerk" the fathers of electro pop and the Swiss band "Yello" with the fantastic voice of Mr. Dieter Meyer and the god of electronic sounds Mr. Boris Blank.

My Garrard TT is from 1965 serial # 12058 - and I am the second owner from early 1970
Service and rebuild new plinths or modifications myself
I also prefer MM or MI carts because they reproduce the sound I prefer from my preferred music genre- that being progressive rock
I also find the combination of moving iron with a phono tube preamplifier particularly attractive. The musical emotions are more sensitive than with a transistor phono . I can also play MC via the transistor Phono, of course there are really great MC Cardridges, but I think the prices for them in Germany are sometimes outrageously high.

Yes I remember, thank you for that. You're not the first to want to tame a Klipsch horn. I've done similar mods to every Klipsch I've owned, and to those of friends. I recently replaced the original driver of the horn in my KLF-10's with a FaitalPro driver that is 107dB's loud. I really had to do some taming to the crossover, but it sounds amazing. A real improvement. The real trick to taming a Klipsch horn is to make sure you keep the 2000Hz "hump" in the frequency response curve. That's what give Klipsch horns their signature sound.
Ultimately, I opted for a voltage divider in front of the horn. (change on the crossover) There is a 3.9 ohm resistor in series in front of the driver anyway. I took several measurements. The goal was to make the MHT driver linearly quieter. With a 10 ohm resistor in parallel in front of the horn, the level became 4db quieter. That was the upper limit and the brilliance was lost. So I groped my way. 22 ohms was still too bright. With 15 ohms it was perfect.I can drive levels up to 106 dB in my music room, because the 2 KHz dominance of the horn was annoying. Of course, the quality and sound properties of the caps, resistors, coils, etc. used also play a very important role in a crossover modification. Iám happy than never before now

cheers to everybody here, I have some days vacations and it´s 10.45 pm in germany, listening to 10 CC first Album from 1975 . Their first hit single " I am not in love " is recorded on the album " the original soundtrack " as well. On the Phonogram Germany Label. Amazing acustical quality at these times.

The good thing is, you still have the original crossovers and your new crossovers look like they have enough room in them to make adjustments.
You may remember, when I send the RF7 Diagram to you, a couple of weeks ago...the red line with the voltage divider

You have to know that I had the coil inductance measured by an electrical engineer. He said it all fits. In addition, my crossover does not match the mirrored image with the parameters of the original crossover. It is modified. The dynamics of the horn were dampened linearly by 2.5 dB. The presence spectrum, especially at high volume, was too dominant and obscured the basic acustic tones and voices, especially in the depth of the stage representation. I have only been using the external crossover for 10 days and am only listening to the new acoustic performance. The first measurement diagram shown above shows the frequency response and the freedom from distortion of the entire sound spectrum. Of course, I do not rule out any later changes, but at the moment I am just amazed at how the RF7 MK II plays.

More cool and unique turntable images. Ones with the separate motor always have a neat design. @MicroMara your whole stereo is a one of a kind rig!
@billybob it will be good to have you spinning more in here again.
My TT is made by the legendary japanese Factory " Micro Seiki " and is about 38 years old. I own it since 1982. Every two years I do services on it, like change of the oils for the disc drive ,oil for the tonearm lift, or tonearm adjustments. Depends on the cardridges that I use. Using Moving Iron only, like Grado´s , Soundsmith, Nagaoka´s or Osawa .

At this point I wanted to say thank you again. Your graphic helped me a lot to implement the arrangement of the coils. Without this graphic, I would have chosen a different arrangement, but this could have led to induction problems. Thanks alot CECAA850 💪 👍

I now follow your tradition in this thread with the illumination of the record on the turntable and integration with cover. It's nicer than just showing the cover of the record you just heard.
I now have a few days to finally be able to listen to music in peace. I still have vacation entitlement from 2019. In Germany you have to take your remaining vacation until the end of March of the following year, which is legally required.Tangerine Dream ... my favorite album is "FORCE MAJEURE". I even have the Clear Cut version

Wow! Lots of descriptive words. Any before and after O scope test results?
Glad you think it's soooooo much better. Maybe Klipsch needs your help?
I am only a small amateur against the engineers at Klipsch, but in the past few days I have tried with a "mini dsp Umik 1, an Omni-Directional USB Measurement Calibrated Microphone measurements at a distance of 39,3701 inch ( = 1 meter ) . The microphone was at a height between Horn and the first bass woofer.
For comparison I have 3 diagrams here.
The first diagram is from the original RF7 MK II. This measurement diagram was published by the German Hi-Fi Magazine "Audio". First axial, the 10 degrees high, 30 degrees, 60 degrees and 90 degrees.
The second diagram shows the measurement of my modified Queen RF7 MKII, axial only.
The third diagram shows the measurement diagram of an RF7 MK III. It was published by the English HiFI magazine Henley Audio UK.
Of course, I don't have the opportunity to carry out really professional measurements at home, because I lack the equipment and soundproof rooms. Nevertheless, I believe that my measurements at least give indications. THD = 0,290 % !
When I bought the RF7 MK II 4 years ago I was in love with her, after the Moddy phases 1 - 5 I loved her ... now I adore her .

Guten Abend bro!
Yes they are, got the first one and it surprised me. Also the treble is really cranked up in the mastering of my cd. I mean like tweeter blowing loud including distortion, can not crank it up... I like my speakers!
cheers my friend, enjoy your wiskey . On my RF7 MK II with the new crossovers, Greta van Fleet sound supple soft in the heights, the mid-tone as with the melt of golden honey colors, the basses rich and dry with the energy of a volcano. The voice of the frontman like that of Jimmy Page. The boys are incredibly good.You also need the 2018 album.
Buy for now, still 01.a.m here.

I'm listening to the American rock group "Greta van Fleet". The albums " from the fires " and anthem of the peaceful army ". I also have everything from "Led Zeppelin" as records. Greta van Fleet are really the reincarnation of Led Zeppelin ". I am thrilled.

See you soon

Just heard these two groups Kenny Burell's "Midnight Blue" recorded in 1967 with the musicians Stanley Turrentine, Major Holly Jr. Bill English, and Ray Barretto.
Then came the album "CONCERTIO" by Jim Hall from 1975. With the musicians Chat Baker, Paul Desmond, Roland Hanna, Ron Carter and Steve Gadd.
Great Stuff .....

I always wondered why Buddy Guy adjusted his guitar with those stringy buzzed high pitch aftereffect tonal qualities.

Yes, this is really a unique effect in blues music with a high recognition value

No middle ground?
I like you fine, but in this I categorize you as "over the top."
I like your power distribution yard analogy. I made a ton of money working in them. Where's the hollow aluminum tubes?
Yes, I know "the golden middle" is mostly the right way. Me ? too extreme? I think spontaneously of Youthman, who has produced a new video on youtube with only "50 pairs" of Klipsch boxes that he owns. I only have 2 speakers ! At least something that Youthman doesn´t have. Good Idea...the hollow alu tubes

Do you still know this soul funk band? With Lionel Richie as front man, Motown at its finest. With the wonderful songs "Easy", "Three times a Lady", "Still" "Brick House".
Then I noticed a long-forgotten disc. MADHOUSE I don't know how I could forget this lady......
Is a production of the label Paisley Park, the label of the unforgettable superstar "PRINCE". A tragedy .......
And I was in a good mood and George Benson played on interpretations of Chuck Berry and Fats Domino with the album "Walking to New Orleans". It is a new release from 2019. Wonderful ...
